fix(ci): swap 4 broken RoboTwin tasks in smoke eval

The smoke eval hit two upstream issues:
- `open_laptop`: bug in OpenMOSS/RoboTwin main — `check_success()` uses
  `self.arm_tag`, but that attribute is only set inside `play_once()`
  (the scripted-expert path). During eval `take_action()` calls
  `check_success()` directly, hitting `AttributeError: 'open_laptop'
  object has no attribute 'arm_tag'`.
- `close_laptop`, `close_microwave`, `place_block`: not present in
  upstream RoboTwin `envs/` at all — our ROBOTWIN_TASKS tuple drifted
  from upstream and these names leaked into CI.

Replace the four broken tasks with upstream-confirmed equivalents
that exist both in ROBOTWIN_TASKS and in RoboTwin's `envs/`:
`adjust_bottle`, `lift_pot`, `stamp_seal`, `turn_switch`.

New 10-task smoke set: beat_block_hammer, click_bell, handover_block,
stack_blocks_two, click_alarmclock, open_microwave, adjust_bottle,
lift_pot, stamp_seal, turn_switch.
